Traffic Sign Recognition System
Reminds you of road sign information of th e current speed limit your vehicle has just
passed through, showing it on the multi-information display and the head-up
display
*.
1 Traffic Sign Recognition System
Not all signs may be displa yed, but any signs posted
on roadsides should not be ignored. The system does
not work on the designated traffic signs of all the
countries you travel, nor in all situations.
Do not rely too much on the system. Always drive at
speeds appropriate fo r the road conditions.
Never apply a film or attach any objects to the
windshield that could obstruc t the camera’s field of
vision and cause the system to operate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s field of vision can cause the
system to operate abnormally. If this occurs, we
recommend that you replace the windshield with a
genuine Acura replacement windshield. Making even
minor repairs within the ca mera’s field of vision or
installing an aftermarket replacement windshield may
also cause the system to operate abnormally. After
replacing the windshield, have a dealer recalibrate the
camera. Proper calibration of the camera is necessary
for the system to operate properly.
To help reduce the likelihood that high interior
temperatures will cause the camera’s sensing system to
shut off, when parking, find a shady area or face the front
of the vehicle away from the sun. If you use a reflective sun
shade, do not allow it to cover the camera housing.
Covering the camera can concentrate heat on it.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 541

Driving
Shows the current speed limit based on either information compiled through the
navigation system* or speed limit signs captured by the front sensor camera. The
system displays the ones that are recognized as designated for your vehicle. The sign
icon will be displayed until the vehicle reaches a predetermined time and distance.
If the system does not detect any traffic signs while you are driving, the sign icon will
not be displayed.
The sign icon also may switch to another one or disappear when:
• The other designated limit is detected.
• You make a turn with a turn signal at an intersection.
■How the System Works1Traffic Sign Recognition System
You can select whether the source of the speed limit
information is the front sensor camera or the
navigation system.
You can also turn off speed limit information. 2 Customized Features P. 359

The Traffic Sign Recognition system may inco rrectly recognize, be slow to identify,
or fail to recognize the traffic sign in the following cases.
■Vehicle conditions
• Headlight lenses are dirty or the h eadlights are not properly adjusted.
• The outside of the windshield is blocked by dirt, mud, leaves, wet snow, etc.
• The inside of the windshield is fogged.
• There are portions remaining to be wiped.
• An abnormal tire or wheel condition (inco rrect sizes, varied sizes or construction,
improperly inflated, compact spare tire
*, etc.).
• The vehicle is tilted due to a heavy load or suspension modifications.
■Environmental conditions
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted onto the roadway.
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• When you drive in the shad ows of trees, buildings, etc.
• Driving at night, in dark areas such as long tunnels.
• Driving in bad weather (rain, fog, snow, etc.).
• A vehicle in front of you is kicking up spray or snow.

The Traffic Sign Recognition system may not operate correctly, such as displaying a
sign that does not follow the actual regulation for the roadway or does not exist at
all in the following cases. u A speed limit sign may display at a higher or lower speed than the actual speed
limit.
• There is a supplementary sign with furth er information such as weather, time,
vehicle type, school zone, etc.
• Figures on the sign are hard to read (electric signs, numbers on the sign are
blurred, etc.).
• The sign is in the vicinity of the lane you are driving in, even though it is not for
the lane, such as a speed limit sign situat ed at an exit or an intersection between
the side road an d the main road.
• There are things that look similar to th e color or shape of the recognition object
(similar sign, electric sign, signboard, structure, etc.).
• A truck or another large vehicle with a sticker of the speed limit sign on the back
is traveling in front of you.

Parking Sensor System*
The corner and center sensors monitor obstacles around your vehicle, and the
beeper, multi-information display and audi o/information screen let you know the
approximate distance between your vehicle and the obstacle.
■The sensor location and range
1 Parking Sensor System*
Even when the system is on, always confirm if there is
no obstacle near your ve hicle before parking.
The system may not work properly when:
•The sensors are covered with snow, ice, mud, or
dirt.
•The vehicle has been out in hot or cold weather.
•There is something nearby that emits ultrasonic
waves or high frequency sounds.
•Driving in bad weather (rain, fog, snow, etc.).
•Any accessories have been put on or around the
sensors.
The system may not de tect these obstacles:
•Thin or low objects.•Sonic-absorptive materials, such as snow, cotton,
or sponge.
•Objects directly under the bumper.
The system may falsely de tect obstacles in the
following situations:
•The vehicle is on uneven su rface, such as grass,
bumps, or a hill.
•When close to other vehicl es with sonar sensors or
other objects that em it ultrasonic waves.
•There is splashing water near the sensors due to
heavy rains, etc.

uuParking Your Vehicle uCross Traffic Monitor

Driving
The system activates when:
• The power mode is in ON.
• The Cross Traffic Monitor is turned on.
2 Cross Traffic Monitor On and Off P. 564
•The transmission is in (R.
• Your vehicle is moving at 3 mph (5 km/h) or
lower.
When a vehicle is detected approaching from a rear corner, Cross Traffic Monitor
alerts you with a buzzer and a displayed warning.
The system will not detect a vehicle that approaches from directly behind your
vehicle, nor will it provide alerts about a detected vehicle when it moves directly
behind your vehicle.
The system does not provide alerts for a vehicle that is moving away from your
vehicle, and it may alert for pedestri ans, bicycles, or stationary objects.
■How the System Works1Cross Traffic Monitor
Cross traffic monitor may not detect or may delay
alerting an approach ing vehicle, or may alert without
an approaching vehicle under the following
conditions:
•An obstacle, such as a nother vehicle and a wall,
near your vehicle’s rear bumper, is blocking the
radar sensor’s scope.
•Your vehicle is moving at the speed of about 3 mph
(5 km/h) or higher.
•A vehicle is approaching at the speed other than
between about 6 mph (10 km/h) and 16 mph (25
km/h).
•The system picks up external interference such as
other radar sensors from an other vehicle or strong
radio wave transmitted fr om a facility nearby.
•Either corner of the rear bumper is covered with
snow, ice, mud or dirt.
•When there is bad weather.
•Your vehicle is on an incline.
•Your vehicle is tilted due to a heavy load in the rear.•Your vehicle is reversing towards a wall, a pole, a
vehicle, and so on.
The rear bumper or the sens ors have been improperly
repaired or the rear bum per has been deformed.
Have your vehicle checked by a dealer.
For proper operation, always keep the rear bumper
corner area clean.
Do not cover the rear bumper corner area with labels
or stickers of any kind.
